Application ledseptember 2, 1920. Serial No. 407,796.

.To all whom 'it may concern:

ll-eit known that l, Renner Nonms, a citizen et the United States,residing at Wytheville, in the county ot VVythe andSt-ate of l/Tirginia,have invented certain new and useiul lm provements in Window-Pulleys andHousing Therefor, of which the follow ing isaspecication. y

This invention relates to pulleys and a 'traine or housing thereforespecially designed Jfor use in connection with. balanced t weightedwindow sashes.

The prime object of the invention is to provide" simple, economical,durable, eiii cient, and novel means for properly supporting and guidingwindow cords.

Another object' of this invention is to so construct my improved devicethat it may be easily and readily mounted in place Without'the labor andexpense of countersinking, mortising, or slotting the window frame; thatit will effectuallyprevent any tendency of the sash cord binding on thepulleys; that it will avoid the chaling and wearing of the cords on thepulleys by any jumping of the cord into the spare between the sash andthe pulley flanges; that it insures against the displacement of the cordfrom the pulleys;`

that it will always maintain its upright and proper position afterhaving and that it distributes the weight o'lieach sash and sash weightover two pulleys in stead. of vone thereby rendering the more ready andeasy manipulation ofthe sliding sashes Vusually fittedu within thewindow frames. L

A further :object `of the invention is to secure the device to the upperand outer face of the `heading and side iamb of the window iframe,respectively, so that one of the pulleys will rest in parallel alinementwith the side liamb, while the other pulley rests in parallel alinementwith the heading of the window frame. y

The 'foregoing and such other objects as may appear from the ensuingdescription are attained by the construction, arrangement, combinationand location of parts hereinafter more fully described, illustrated inthe accompanying drawings. and particularly pointed out in the claimsappended hereto, it being understood that slight changes in the preciseform, proportions and minor details of the construction may be rea5`sorted to `without departing from the spirit been secured,`

of the invention or sacrificing any of the advantages thereof.` "In theaccompanying drawings forming thptart othisspeccation it will be seenFigure l, is a sectional elevation of the im proved devicelernbojdyingmy invention. Fig?, isaplan, showing the device artly 1n section andsecured to the Window rame, and j n Fig. 3, is a perspective showing thehousifng detached and the pulleys removed thererom. "Similar charactersof reference are employed to designate like parts "throughoutthe'several ligures of thedrawings.`

Incarrylng out my invention as illus` trated i( have shown in Fig. l, myimproved devicesecured to the upper right hand corner of a window frame.A designates theheading or upper member of a 'window frame and B, theside jamb of the` frame',

` while the numeral `1, indicates a frame `0r housing made of anysuitable metal and preferably stamped or forged from `a single plecelofmetal by'onegstroke of a suitable stampmgor pressingmachine. Said frameor housing is preferably formed with later? a,lly extended verticalflanges 2, eachl flange having an opening 3 therethrough or thereception of" a securing screw or lnail 4 whereby said angesarerigidlyisecured to the `side ,janib, and lateral ly extended horiZontally `arranged {ianges 5, eac'h having an opening 6, adapted toreceive suitable screws or nails"7 for xedly `securing said flanges tothe `upper surface' of the windowrame heading, said heading having anopening` bored therethrough for the reception loia metallic "guidesleeve 8, through `which the sash cord 9 is adapted to be easily andreadily guided in its up and down movement, one end of the sash cordbeing attached in any suitable manner to the window sash (not shown),while its other end is securely fastened to a balance weight l0. t

It will be perceived that the frame or housing 1, is provided with aplurality of openings l1 Within which is mounted a spindle or bearingwhich may be a tube, or a solid rod 12 capable of being fixed againstendwise displafement by riveting the ends thereof, each of said rods l2carrying a pulley 13 ot the conventional type or kind. t

It will further be seen that the frame or housing is formedwith arounded upper and which materially assists in passing the sash cord overthe pulleys and through the said frame, as well as to preventanydisplaeement of the sash cord at all times, and the inner fare of thehousing being formed with two sets of laterally extended flanges, oneVset being arranged at a right angle with respect to the other, andsecured to the outer side of the side jamb and header of the windowframe, respectively, the tendency of the frame is to always remain inits fixed position in proper alinement with Athe sashcord, therebyavoiding the chafing andusual wear on the sash cord occasioned by thejumping of the cord. into the space between the sash and the pulleyflanges,l and further, the location and arrangement of my d evice avoidsthe necessity for slotting, mortising or countersinkingthe outersurface,

p window frame, which is the usual custom for the connection of pulleysand pulley frames to the window frames, and one pulley being inparallelalinement with the outer face of the side jamb and the otherpulley arranged in horizontal alinement with the outer surfaeefof theheader 'theweight is distributed over,A the two pulleys, `thus avoidingall tendency` of the binding of the pulleys, and thereby permitting-moreeasy and smooth operation thereof, as will be readily understoodg 1 itr.will also be seen that since the sash cord passes through a metallicsleeve fitted within the header in alinement with the pulleys andhousing or frame, said cord cannot get out of place and the pulleys andhousing are naturally held in their proper position by the weighted sashcord, there being no tendency whatever for the housing to becomeunbalaneedor displaced. TWhile I have shown but one of my improveddevices for the purposes hereinbefore referredto, it will be understoodthat, two ofsuch Vdevices are employed foreach window sash,i two beingsecured on each upper and outer sideof the window frame, one fortheiupper sash frame and another for the lower sash frame, as will bereadily obvious. Having thusdescribed my invention what l claim anddesire to secure by Letters Patent is zl. A device of the characterdescribed, comprising a housing formed from a single piece of metal witha horizontal and vertical extension, each extension having formedintegral therewith a laterally extended flange at each side thereofforming a portion of the inner face of said housing and adapted to besecured to the outer face of the heading and side jambof a window frame,respectively, and a pulley secured within each of said extensions.

2. A device of the character described comprising a housing formed witha rounded upper and rear outer surface and with vertical laterallyextended flanges and horizontal laterally extended flanges, said flangesbeing secured to the outer surface of the side jamb and the outersurface of the heading respectively, and a pulley secured within thehousing in parallel alinement with the vertical flanges, and anotherpulley secured within the housing in parallel alinement with thehorizontal fianges.

3. A device of the character described comprising a housing formed of asingle piece having a rounded upper and rear surface with verticallaterally extended fianges and horizontal laterally extended flangesforming the inner of said housing, said fianges being fixedly secured tothe outer surface of the side jainb and the outer surface of theheading, respectively, and a plurality of pulleys secured within saidhousing, each pulley heilig in alinement with said flanges.

. el. A device of the character described comprising a housing formed ofa single piece of metal with vertically extended and horizontallyextended flanges arranged at a. right angle with respect to each other,said flanges being secured to the outer face of the side jamb andthe-outer face of the heading, and a plurality of pulleys secured withinsaid housing, one pulley being in parallel alineinent with the sidejamb, and the other pulley in parallel alinement with said heading.
